UNASSIGNED: Under-5 pneumonia mortality remains high in low-income countries. In 2014 the World Health Organization (WHO) advised that children with chest indrawing pneumonia, but without danger signs or peripheral oxygen saturation (SpO 2) < 90% be treated in the community, rather than hospitalized. In Malawi there is limited pulse oximetry availability.
UNASSIGNED: Secondary analysis of 13,413 under-5 pneumonia cases in Malawi. Pneumonia associated case fatality ratios (CFR) were calculated by disease severity under the assumptions of the 2005 and 2014 WHO Integrated Management of Childhood Illness (IMCI) guidelines, with and without pulse oximetry. We investigated if pulse oximetry readings were missing not at random (MNAR).
UNASSIGNED: The CFR of patients classified as having non-severe pneumonia per the 2014 IMCI guidelines doubled under the assumption that pulse oximetry was not available (1.5% without pulse oximetry vs 0.7% with pulse oximetry, P<0.001). When 2014 IMCI guidelines were applied with pulse oximetry and a SpO 2 < 90% as the threshold for referral and/or admission, the number of cases meeting hospitalization criteria decreased by 70.3%. Unrecorded pulse oximetry readings were MNAR with an adjusted odds for mortality of 4.9 (3.8, 6.3), similar to that of a SpO 2 < 90%. Although fewer girls were hospitalized, female sex was an independent mortality risk factor.
UNASSIGNED: In Malawi, implementation of the 2014 WHO IMCI pneumonia guidelines, without pulse oximetry, will miss high risk cases. Alternatively, implementation of pulse oximetry may result in a large reduction in hospitalization rates without significantly increasing non-severe pneumonia associated CFR if the inability to obtain a pulse oximetry reading is considered a WHO danger sign.

To develop an expert consensus statement regarding persistent pediatric obstructive sleep apnea (OSA) focused on quality improvement and clarification of controversies. Persistent OSA was defined as OSA after adenotonsillectomy or OSA after tonsillectomy when adenoids are not enlarged.
An expert panel of clinicians, nominated by stakeholder organizations, used the published consensus statement methodology from the American Academy of Otolaryngology-Head and Neck Surgery to develop statements for a target population of children aged 2-18 years. A medical librarian systematically searched the literature used as a basis for the clinical statements. A modified Delphi method was used to distill expert opinion and compose statements that met a standardized definition of consensus. Duplicate statements were combined prior to the final Delphi survey.
After 3 iterative Delphi surveys, 34 statements met the criteria for consensus, while 18 statements did not. The clinical statements were grouped into 7 categories: general, patient assessment, management of patients with obesity, medical management, drug-induced sleep endoscopy, surgical management, and postoperative care.
The panel reached a consensus for 34 statements related to the assessment, management and postoperative care of children with persistent OSA. These statements can be used to establish care algorithms, improve clinical care, and identify areas that would benefit from future research.

Continuous pulse oximetry monitoring (cSpO2) in children with bronchiolitis does not improve clinical outcomes and has been associated with increased resource use and alarm fatigue. It is critical to understand the factors that contribute to cSpO2 overuse in order to reduce overuse and its associated harms.
This multicenter qualitative study took place in the context of the Eliminating Monitor Overuse (EMO) SpO2 study, a cross-sectional study to establish rates of cSpO2 in bronchiolitis. We conducted semistructured interviews, informed by the Consolidated Framework for Implementation Research, with a purposive sample of stakeholders at sites with high and low cSpO2 use rates to identify barriers and facilitators to addressing cSpO2 overuse. Interviews were audio recorded and transcribed. Analyses were conducted using an integrated approach.
Participants (n = 56) included EMO study site principal investigators (n = 12), hospital administrators (n = 8), physicians (n = 15), nurses (n = 12), and respiratory therapists (n = 9) from 12 hospitals. Results suggest that leadership buy-in, clear authoritative guidelines for SpO2 use incorporated into electronic order sets, regular education about cSpO2 in bronchiolitis, and visual reminders may be needed to reduce cSpO2 utilization. Parental perceptions and individual clinician comfort affect cSpO2 practice.
We identified barriers and facilitators to deimplementation of cSpO2 for stable patients with bronchiolitis across children\'s hospitals with high- and low-cSpO2 use. Based on these data, future deimplementation efforts should focus on clear protocols for cSpO2, EHR changes, and education for hospital staff on bronchiolitis features and rationale for reducing cSpO2.

Newborn resuscitation guidelines recommend initial assessment of heart rate (HR) and initiation of positive pressure ventilation (PPV) within 60 s after birth in non-breathing newborns. Pulse oximeter (PO) and electrocardiogram (ECG) are suggested methods for continuous HR monitoring during resuscitation. Our aim was to evaluate compliance with guidelines and the efficacy of PO versus ECG monitoring in real-life newborn resuscitations.
In this prospective observational study, we video recorded resuscitations of newborns ≥34 weeks of gestation receiving PPV at birth.
104 resuscitations were analysed. Median (IQR) time from birth to arrival at the resuscitation bay was 48 (22-68) s (n = 62), to initial HR assessment 70 (47-118) s (n = 61), and to initiation of PPV 78 (42-118) s (n = 62). Initial HR assessment (stethoscope or palpation) and initiation of PPV were achieved within 60 s for 35% of the resuscitated newborns. Time to initial HR assessment and initiating PPV was significantly longer following vaginal deliveries than caesarean sections: 84 (70-139) versus 44 (30-66) s (p < 0.001) and 93 (73-139) versus 38 (30-66) s (p < 0.001). Time from birth and sensor application to provision of a reliable HR signal from PO versus ECG was 348 (217-524) (n = 42) versus 174 (105-277) s (n = 30) (p < 0.001) and 199 (77-352) (n = 65) versus 16 (11-22) s (n = 52) (p < 0.001).
Initial HR assessment and initiation of PPV were achieved within 60 s after birth in only 1/3 of newborn resuscitations. When applied for continuous HR monitoring, ECG was superior to PO in time to achieve reliable HR signals in real-life resuscitations.

Cerebral Oximetry by Near-infrared Spectroscopy (NIRS) has been used in cardiovascular anesthesia, but there was no guideline of regional cerebral oxygen saturation measured by cerebral oximetry by NIRS. This guideline provides recommendations applicable to patients at a risk of developing cerebral ischemia in cardiovascular surgery. Guidelines are intended to define practices meeting the needs of patients in most, but not all, circumstances, and should not replace clinical judgment. The Japanese Society of Cardiovascular Anesthesiologists (JSCVA) Task Force on Guidelines make an effort to ensure that the guideline writing committee contains broad views in using cerebral oximetry. Adherence to recommendations could be enhanced by shared decision making between healthcare providers and patients. This guideline was focused on cerebral oximetry of pediatric and adult cardiovascular disease. We hope this guideline would play an important role in using cerebral oximetry by measured NIRS.

OBJECTIVE: Bronchiolitis is a common respiratory illness and is a leading cause of hospitalisation in infancy. We aimed to appraise three recent national bronchiolitis guidelines produced by the Australasian Paediatric Research in Emergency Departments International Collaborative, the National Institute for Health and Care Excellence in the UK and the American Academy of Pediatrics.
METHODS: A group of final-year medical students and one senior clinician used the AGREE II tool to appraise each guideline in two stages. First, two students appraised each guideline independently and presented their results. Second, two self-selected students met with the senior clinicians to review all scores to ensure completeness of the appraisal and consistency of AGREE II application.
RESULTS: The guidelines scored well overall, with particular strengths in the domains of clarity of presentation, scope and purpose and rigour of development. Comparison of the recommendations across each guideline demonstrated a high degree of consistency. Notable differences included recommendations for the role of palivizumab in prevention of bronchiolitis, the use of continuous pulse oximetry monitoring in the hospitalised patient and the value of respiratory virus testing.
CONCLUSIONS: Our appraisal of bronchiolitis guidelines from three high-income countries demonstrated that they were of high quality, with substantial areas of agreement. Most aspects of clinical practice should be uniform for this common paediatric condition. Areas of guideline weakness were in the domains of applicability and editorial independence. We identified three areas of controversy where further research is needed to support stronger evidence-based recommendations.
